Title: Disk cartridge
Inventor: MIZUTANI HIKARI
IPC: G11B23/03
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To prevent a shutter which slidingly opens and closes a window hole for reading and writing a signal from being pressed and intruded into the window hole by forming the shutter of a disk cartridge having such shutter of a polypropylene (PP) resin having a prescribed modulus of elasticity in bending. SOLUTION: The shutter 4 is molded of the highly crystalline PP resin which is prepd. by incorporating 10 to 2wt.% inorg. fillers, such as talc or calcium carbonate, into PP and has a melt flow value of >=30g/10min and the modulus of elasticity in bending of 20,000 to 25,000kgf/cm<2> . The haze value of the resin is confined to <=50% to make the disk 1 seeable through. As a result, even if the shutter 4 is formed as small and thin as possible, the shutter is not easily deflected by pressing and is prevented from dropping or submerging into the window hole 3. The damage of the disk 1 is thus prevented and the smooth sliding opening and closing are assured.
